    Markov modulated periodic arrival process offered to an ATM multiplexer
    (IEEE, 1993-11-12) Akar, Nail; Arıkan, Erdal
    When a superposition of on/off sources is offered to a deterministic server, a particular queueing system arises whose analysis has a significant role in ATM based networks. Periodic cell generation during active times is a major feature of these sources. In this paper a new analytical method is provided to solve for this queueing system via an approximation to the transient behavior of the nD/D/1 queue. The solution to the queue length distribution is given in terms of a solution to a linear differential equation with variable coefficients. The technique proposed here has close similarities with the fluid flow approximations and is amenable to extension for more complicated queueing systems with such correlated arrival processes. A numerical example for a packetized voice multiplexer is finally given to demonstrate our results.

    A natural language-based interface for querying a video database
    (Institute of Electrical and Electronics Engineers, 2007-01) Küçüktunç, O.; Güdükbay, U.; Ulusoy, Özgür
    The authors developed a video database system called BilVideo that provides integrated support for spatiotemporal, semantic, and low-level feature queries. As a further development for this system, the authors present a natural language processing-based interface that lets users formulate queries in English and discuss the advantage of using such an interface. © 2007 IEEE.
